Removing postgres -f command line option

While looking at Shigeru Hanada's foreign join pushdown patch, I noticed 
a command line option that I didn't know to exist:

$ postgres --help
...
Developer options:  -f s|i|n|m|h    forbid use of some plan types

That doesn't include all the options we support, the documentation 
lists: s|i|o|b|t|n|m|h. These are aliases for enable_* planner options, 
e.g -fs is equal to enable_seqscan=off.

That seems completely useless to me, because you can also do "-c 
enable_seqscan=off". Any objections to removing the -f option altogether?
